Career
He played with the Geelong Football Club in the Australian Football League (American Federation of Labor-Congress), Portuguese Adelaide in the SANFL and Geelong Supercats in the National Basketball League (NBL). Crothers was drafted to the Geelong Football Club, from Grovedale, with the 113th pick of the 1989 VFL Draft. Unable to break into the team, Crothers went on to join the Geelong Supercats and made his NBL debut in 1991, playing in a side which included a young Shane Heal.
He also played NBL in 1992 but left the following year when he was again drafted to the American Federation of Labor-Congress, previously VFL. His American Federation of Labor-Congress career consisted of just four games but he was a part of a strong team which made and lost the Grand Final in both seasons he was at the club, 1994 and 1995.
Playing as a ruckman, he had seven hit-outs and seven disposals on his league debut, against North Melbourne late in the 1994 American Federation of Labor-Congress season. His appearances in 1995 were limited to games against Collingwood and Richmond, the latter at the Melbourne Cricket Ground.
Crothers had become the second person, after Michael Parsons, to compete in both leagues. He also returned to basketball and competed with the West Adelaide Bearcats in the Central Australian Basketball League.
